Ah, Golden Ales. A beer that belies its simplicity with elegance. As of yet, it's the only style that's inspired me to make several iterations.
I find this surprising in that they're often thought of as beers that aren't terribly interesting. However, they are an excellent way to gauge one's brewing progress. If you can brew a tasty beer with one or two malts, one hop variety, and a fairly neutral yeast, I'd say you're well on your way to becoming a great brewer.
The last Golden Ale I brewed had a slight off-aroma that I'm still puzzled over. I feel as though I should be able to nail it on the head as I've gone through the BJCP exam twice now and have been judging and brewing for about two and a half years now. However, I'm still at a loss to describe it to my satisfaction. My best guess is that it's a fusel alcohol aroma that I had not come across before. It smells to me as I imagine fermented corn sugar would smell. I'm not sure precisely where I got this notion, but it's the one firmly implanted in my head.
All that being said, I think I'm going to make many more Golden Ales in the future. I don't have a signature beer, but I think with some work, this could be it. There could be a whole series of them. It would also serve as a great way to really get to know my base grains and hop varietals.
The first will be Maris Otter and homegrown Centennial. I'll update as things progress.
